As the requirements of lift operators and users become increasingly complex, lift and component manufacturers are faced with the challenge of introducing innovative products to create distinctive profiles for their brands. TÜV SÜD supports its worldwide customers in this process. At the Interlift international trade fair to be held in Augsburg, Germany, from 15 to 18 October 2013, the global service provider will provide information on modernisation and energy efficiency of lifts and on certification of lifts and their safety components (Hall 7, Stand 7178).
“Because users make specific demands with respect to lift safety, ease of operation and availability, lift operators are compelled to maintain their systems in line with the state of the art”, explain the modernisation experts at the Lifts and Machinery unit of TÜV SÜD Industrie Service GmbH. Overarching issues of safety engineering, legal and business aspects join design considerations as the main areas of concern. Thanks to modernisation services built on modular structures, actions taken can be tailored to the needs and wishes of the customer. TÜV SÜD's modernisation experts form interdisciplinary teams that support implementation as part of an integrated testing and inspection programme, and provide official acceptance of renovations and modifications.
Efficient components – VDI Guideline 4707, Sheet 2
“Energy savings of up to 30 per cent can be made by using modern technologies” say the TÜV SÜD experts in energy-efficient lift systems. Improvements in energy efficiency may possibly be achieved by simply renewing specific key lift components instead of replacing the entire lift. This year, the VDI Guideline 4707 with its new Part 2 opened the door for standardised calculation of energy consumption by individual components. Based on the newly published guideline “VDI 4707 part 2”, TÜV SÜD also provides energy efficiency classification for individual lift components. TÜV SÜD offers certificates for “Energy-Efficient Lift Systems”, “Energy-Efficient Component Series” and “Energy Efficiency Calculation Procedures” in line with VDI Guideline 4707-1 and -2, which guarantee to provide robust overall energy assessments for manufacturers and operators.
The VDI Guideline 4707-1 describes an internationally recognised method of assessing and identifying the energy efficiency of lifts. By applying standardised criteria, comparisons of various lift system types – even spanning different manufacturers – can be drawn up and classified into efficiency categories A to G. In future, a Part 3 will be added to the VDI Guideline 4707 to serve as a further benchmark for the assessment of types such as platform, service and small-scale service lifts.
Certification of lifts and safety components
The Lift Directive 95/16/EC is currently undergoing revision by the EU Commission, with publication of the final version scheduled for the end of the year. After this point a transitional period of two years will apply, during which the individual member states must implement the Directive in their national laws. While the conformity assessment procedures for lifts and their safety components will not be changed, the harmonised standards from the EN81 series, which define safety levels for lifts, are being revised. Standards EN 81-1 and EN 81-2 will be replaced by EN 81-20 (requirements) and EN 81-50 (testing and calculation regulations). New requirements will be added with respect to landing doors, lift-shaft ladders and the definition of protective spaces.
TÜV SÜD recommends that safety component manufacturers and assembly shops address these new regulations and changes to technical requirements at an early stage. The lift experts at TÜV SÜD provide support for lift operators in areas such as compliance with the Industrial Health and Safety Ordinance, to increase the safety and availability of lift systems. Global efforts focus on establishing a balance between efficiency, sustainability and safety.
